二氯均三嗪反應型紫外線吸收劑的合成與應用

摘 要： 為解決C.I.活性紅24∶1染色棉織物在日光照射下容易褪變色以及市場上缺乏對棉織物具有耐久反應性整理光穩定化助劑的問題，在苯并三唑紫外線吸收劑結構中引入二氯均三嗪活性基和磺酸基，設計開發了一種兼具優良水溶性和反應性且在合成過程中無需使用催化劑的新型紫外線吸收劑R1，并通過質譜、紅外光譜、紫外-可見吸收光譜、核磁共振氫譜對產物分子結構進行表征；將R1分別應用于未染色棉織物和C.I.活性紅24∶1染色棉織物，測試了固著率、UPF值、光致褪色率、耐光色牢度與耐洗性。結果表明：R1在未染色棉織物上的固著率達到85.47%，UPF值為118.97，染色織物表現出優異的防紫外線透過能力；R1在染色棉織物上的固著率為65.41%，光致褪色率降低了5.07%；耐光色牢度提升了1.0級，皂洗10次后，UPF損失率降低不超過3.20%。反應性紫外線吸收劑R1與棉織物反應機理與活性染料相近，將R1整理到棉織物及染色制品上，對提升棉織物防紫外線性能、染色棉織物耐光性能以及耐久性具有較好的應用價值。

Abstract：To solve the problem that C.I. reactive red 24∶1 dyed cotton fabrics are easy to fade under sunlight and that the market lacks of light stabilization additives with durable reactivity for cotton fabrics， dichloromistriazine active group and sulfonic acid group were introduced into the structure of benzotriazole UV absorbers. A new UV absorbent R1 with excellent water solubility and reactivity was designed and developed without the use of catalysts in the synthesis process， and the molecular structure of the product was characterized by mass spectrometry， infrared spectroscopy， UV-vis absorption spectroscopy and hydrogen NMR spectroscopy. R1 was applied to an undyed cotton fabric and C.I. reactive red 24∶1 dyed cotton fabric， and the fixing rate， UPF value， photofading rate， color fastness to light and washable ability were tested. The results showed that the fixed rate of R1 on the undyed cotton fabric reached 85.47%， the UPF value was 118.97， and the dyed cotton fabric showed excellent anti-ultraviolet transmission ability. The fixation rate of R1 on the dyed cotton fabric was 65.41%， and the photofading rate was reduced by 5.07%. The color fastness to light was increased by 1.0 level， and the UPF loss rate was reduced by no more than 3.20% after soaping for 10 times. The reaction mechanism of the reactive UV absorbent R1 with cotton fabrics is similar to that of reactive dyes. When R1 is finished on cotton fabrics and dyed products， it has a good application value to improve the UV resistance of cotton fabrics， and light resistance and durability of dyed cotton fabrics.
